Emissions of carbon dioxide are one of the chief sources of the air pollution that is causing the proven upheaval in the climate. Nearly 5 metric tons of carbon is released when an acre of coniferous forest burns. In 2006 alone, 9.87 million acres of forest in the United States were lost to wildfires. Even if it is more likely that they are started deliberately to clear vast areas for agriculture, many fires are accidentally caused by leisure activity.
Preserve the planet’s forests: Don’t light fires.
